Seat Toledo ABS Fault

I have a problem with my 2008 Seat Toledo with a gasoline engine. The ABS lamp is on, and the ABS system isn't working. I scanned it, and it shows a lateral acceleration sensor fault. Could a defective control unit be the cause?

It sounds like a faulty lateral sensor in your ABS unit. The ABS light and system failure are classic symptoms, and the error code confirms it. Does the light come on immediately when you start the car, or only when you start driving and cornering?

The light usually comes on after driving a few meters, especially when turning. Is it a big job to replace the lateral sensor? Is it something I could do myself?

Replacing the lateral sensor usually means replacing the entire ABS control unit, as it's integrated. It's not a simple DIY job because it involves coding the new unit to your car. If you're not experienced with car electronics, I'd recommend taking it to a workshop. A faulty lateral sensor will affect the vehicle stability and is a safety concern.

Thanks for the assistance. The garage confirmed the lateral sensor in the control unit was faulty. It cost 1000€ to repair, but the ABS and electronic stability are now working correctly.
